Application filed Apri19, 1909. Serial No. 488,954.

To all whom it may concern:

Be it known that I, Axonnw C. BoL'roN, a citizen of the United States, and resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Wrapping-Machines, of which the following is a specification.

My invention relates to wrapping machines and more particularly to machines for wrapping hose with fabric while the rubber is in a green state and prior to vulcanizing and has for its ob'ect to provide a machine of this character which is simple in construction and easy of operation. Heretofore in many instances, it has been customary to wrap hose in this manner by hand, resulting in great unevenness of wrapping and tension and also in a great expen iture of time. My invention is intended to overcome these (litliculties and to wrap the hose evenly and to apply the fabric under a uniform and even tension. In wrapping hose by hand it is necessary to place the hose on a mandrel so as to enable the hose to be properly manipulated. With my machine if desired the use of the mandrel may be omitted and during the curing operation the hose may be filled with air under pressure by means of suitable mechanism. My machine may also be used for unwrap )ing the fabric from the hose after it has l) on cured.

Other objects of my invention will appear from the description hereinafter and the features of novelty will be pointed out in the appended claims.

Reference is to be had to the accompany ing drawings in which- Figure 1 is a side elevation of my improved machine; Fig. 2 is a cross section thereof on the line 22 of Fig. 1; Figs. 3 and 3 are horizontal sections on the line 33 of Fig. 1; Figs. 4 and 4 are sectional views on the line 44 of Figs. '3 and 3'; Fig. 5 is a sectional view on the line 55 of Fig. 1; Fig. 6 is a sectional view on the line 6-6 of Fig. 3; Fig. 7 is a detail sectional view of one of the feed tube ends; Fig. 8 is a cross section thereof on the line 8-8 of Fig. 7; Fig. 9 is an elevation partly in section of the opposite end of the feed tube; Fig. 10 is an end view thereof; Figs. 11, 12 and 13 are diagrammatic views in cross section showing the longitudinal wrapping at different steps of the winding operation and Fig. 14

is an elevation of the hose after it has been wrapped.

A 1s a su port on the upper end of which is located tie journal box B in which the tubular shaft C is arranged to rotate. D is a gear wheel secured to said shaft C to rotate therewith and which meshes with a gear wheel E carried by the driving shaft E. This driving shaft E is journalecl in a bearing A on the frame A and a support A and has mounted thereon the fast pulley F and the loose pulley F. The shaft E further carries the inion G which meshes with a gear wheel G journaled on a stud Gr secured to the frame A, which wheel G in turn engages a pinion H. The pinion H is mounted on a shaft H journaled in bearings H and H, on which shaft H is also located a worm ear H. The said worm gear H is located between and meshes with worm wheels I, I secured to the lower ends respectively of upright shafts I, I The shafts I and I are mounted to rotate in bearings I secured to a stationary support 1 and carry at their upper ends, the feed rollers I and P.- These feed rollers are made with concave peripheries and if desired may be covered with rubber or similar material to prevent laceration of the hose and to insure a better grippin action.

A stationar feed tube or guide J is supported and 0 am ed against rotation in a bearing J carrie by an arm J 2 which is secured to the frame A. The said tube J extends through and beyond the tubular shaft 0 and is provided at one end with a removable split bushing J a the pur ose of which will be more fully describe hereinafter. The tubular shaft O has secured to its one end a removable collar C fastened in position by means of a clamp nut 0 This collar C is formed with a reduced tubular portion C arranged in axial alinement with the feed tube J and having an internal diameter correspondin to the internal diameter of the bushing The said reduced )ortion C is slotted len thwise as indicated at C and is formed wit a projection C extending outwardly therefrom adjacent to the slot G.

K is an arm secured to the tubular shaft C to rotate therewith and carries a short wraper guide K. The said arm is weighted as indicated at K and further has the inner end of a second wrapper guide K secured thereto which guide K extends at an angle from the said arm and has its outer end in close proximity to the rojection C of the collar C. The gui e K is provided throughout a portion of its extent with spaced cross pins K under and over which the fabric passes from the solid portion K of the wrapper guide K. The outer end of the said guide K is also secured to the tubular shaft C as indicated at K. A reel L is loosely mounted on the tubular shaft C between the arm K and a collar L secured against movement on said shaft C by a set screw L and is arranged to contain the su ply of fabric L with which the hose is to iie wrapped spirally.

A standard M is secured to the support A and has secured to it near its free end a bearing M for the bevel inion M This bevel pinion M is provi ed with an annular groove M into which extends a pin M to maintain said bevel ear in position against vertical movement w iile permitting free rotation thereof. A spindle N extends through said bevel pinion M and is keyed thereto by means of a spline N. The spindle N' carries at its upper end the wrapping disk N which is provided with bristles N arranged to engage and wrap the fabric about the hose. The lower end of said spindle N en ages and is supported by a washer N locate above an adjusting screw N having a screw thread engagement with the bearing M. Hook-like members N are secured adjustably to lugs N carried by the support A". The members N are provided with slots N and are fastened in their adjusted position by screws N and further extend over the hose to hold it against risin when the wrapping disk N is operated. short shaft N is journaled in a bearing N secured to the standard M and carries a bevel gear N" in mesh with the bevel pinion M and also carries a s rocket or belt wheel N. This sprocket or elt wheel N is connected by means of a sprocket chain or belt N with a similar sprocket or belt wheel N secured to the power shaft E. The wrapping disk N is so located as to have its center in a vertical plane corresponding to the axis of the shaft C. A trough O is secured on a support A beneath another trough 0 located at a distance above the trough O which trough O has rotatably mounted thereon a reel 0 arranged to carry the fabric O which is wrapped about the hose longitudinally. The trough 0' contains a liquid and is mounted on Standards 0 and O secured respectively to the support A and the trough O. Rollers P and P are mounted between the standards 0 near opposite ends thereof and s aced rods P extend from one standard 4 to the other hetweenthe said rollers P and P.

Q'is a curved guard having itsends secured'to opposite sides of the support A and carrying the screening Q. The said guard and screening are located adjacent to the arm K and are intended as a protection for the operator against injury by the arm K as it travels around.

In operation the hose It in its green state is passed over the wrapping disk N and the fabric is passed over the roll 1- and then in and out over the rods P and is drawn under the roll I" up to the disk N. The said fabric is then placed on the hose over which ithangs in the shape of an inverted U as shown in Fig. 11 and is n'iaintained in position by the members N. This fabric is now wrapped longitudinally about the hose by hand and the wra ped hose is then inserted into the tube J ant pushed through until the end thereof projects through the said tube. This projecting end with the fabric 0 thereon is then wrapped spirally by hand with the fabric L for a short distance or until the end of the hose enters the space between the rollers I and 1 If the machine is now started the rollers I and I will draw the hose along through the tube J which thus serves as a guide therefor. As the hose is thus drawn along the disk N will also be rotated by means of the sprockets N, N and the chain N. The fabric 0 is meantime also drawn along and the one portion 1 thereof is folded or wrapped under the hose as shown diagrammatical y in Fi 12, by means of the part of the bristles h which travel in the direction of the arrow .2 in Fig. 3. As the hose now continues in 1 its travel and as the portion 3 of the fabric 0 reaches the part of the bristles N which rotates in the opposite direction as indicated by the arrow 4 in Fig. 3 this port-ion 3 will be folded or wrapped under the hose and over the end of the portion 1 as shown in Fig. 13. It is to be understood that the fabric 0 is maintained in a moist condition by a liquid, referably water, in the trough O and for t iatreason adheres to the outer surface of the hose. ()wing to the fact that the bristles N are flexible and the upper ends thereof are located in a plane slightly higher than the lower part of the hose, the said bristles will be bent on passing under the hose and will exert a sweeping action on the fabric as they return to their normal position, thus wrapping it securely about the hose and smoothing out any wrinkles which may occur. Durin r this operation the hose with this first longitudinal wrapping O is gradually advancing, and as it leaves the end of the tube J is spirally wrapped with the second wrapping L in the following manner. As ower is applied to the shaft E the gear a will be rotated and will consequently rotate the gear D and with it the tubular shaft C. Owing to the fact that the arm K is secured to said shaft C, the rotation thereof'will cause the end of said arm the longitudinal Wrapping O El e i thereof aboutthe hose.

The pins K serve to keep, fabric under s sli tension. so as toinsure a. secure Wrap dliis fabric L also preferably applied to the in a In state as this condition the tahric adheres to the wrapping O end-is also easier manipulate and smooth out. It is to be understood that the feed rollers I and 1 are rotated at a speed to feed the hose in the required manner to properly Wrap the hue spirally and longitudinally. The feed roll as I and I are operated through the ins diuin of the worm Wheels 1 and I and The shaft H is rotated by means of the gear H, the gear G and the pinion'G Which is mounted the driving shaft EC If the/ho e to Wrappeddsof smellerdiamcte i 2 J, "wiring and collar is, inside diameter slightly side diameter of the hose are SUbSL the bushing and collar used before, i ing bushings and collars of varying sizes all diameters of hose up to the diameter 0 the tube 5 can be accommodated.

After the preliminary Wrappiu it will continue to operate indefinitely, it being understood that each new length of hose to be Wrapped is attached to the end. of the preceding length of hose and drawn along the clay. The Wrappers are cut when. is desired to separate the lengths of hose. Wit-h my machine both Wmppings are automatically, uniformly and quickly applied under an even tension. and Without in Mes.
